There were no planes. Look at all videos of planes, do you see any company logos or signatures, colors, and reflection or refraction on the paint? No you don't they are just grayed 3D models. A mainly aluminum plane cannot cut through steel.
How could a plane tire wind up on a pile of debris if the each tower fell after 45 minutes? They tire would have to climb through at least 20 stories of crumbling steel and concrete even if it was lodged into a floor or the tire had to shoot up into the air for at least 23 minutes then fall for 23 more minutes and slowly land onto of a pile.
